Features SLES 11 for System z


SUSE® Linux Enterprise Server for System z 11New Features in GA Version

Dynamic add/remove of CPU and memory: resources of a Linux guest under z/VM can be adjusted while running. A pool of CPUs are dynamically given to a Linux guest and used as needed

Vertical CPU management: helps get the most performance out of System z10 servers by being aware of the server's NUMA characteristics

Linux CPU Node Affinity: improves performance by scheduling processes to the optimal node where the CPU is associated, exploiting the new System z10 CPU node topology

Modularization of qdio and thin interrupts: Make the thininterrupt layer independent from qdio and improve the codelayering in the qdio module. This provides for additional performance enhancements.

= SLES unique feature


Performance analysis in the disk subsystem: gives performance analysts the same type of view into SCSI over Fibre Channel Protocol that they have with mainframe Direct Access Storage Devices (DASD)

DS8000 support Large volume support architecture: use use one large volume, instead of multiple small volumes, for your large amount of data. You no longer need to combine and manage various small disks anymore. This gives you much better performance and data consolidation.

Support of HPF TCW command interface in DASD driver configuration support: lowers overhead of subchannel operations and increases performance for database serving

FCP adjustable queue depth: Customizable queue depth for SCSI commands in zfcp. In the past was at constant 32 queue entries. Improves performance


SUSE® Linux Enterprise Server for System z 11New Features in GA Version (c'd)


SUSE® Linux Enterprise Server for System z 11 New Features in Service Pack 1

Suspend / Resume support: stop a running instance and later continue operations. A suspended Linux instance does not require memory or processor cycles. gives you better performance, resource utilization, and power savings

Automatic IPL after dump: extension to the shutdown action interface which combines the actions dump and reipl, helps increase availabity and minimize downtime, as well as keep management and service costs low

Cross architecture debugging: System z core dumps can be analyzed on x86 systems, negating the need for a duplicate System z server

System z kernel message documentation: messages in System z related code, script to generate a man page for every kernel message related to s390x



SUSE® Linux Enterprise Server for System z 11 New Features in Service Pack 1 (c´d)

Next generation crypto HW device driver exploitation (CEX2/CEX3): new System z crypto hardware features and performance improvements are exploited by SUSE Linux Enterprise Server for System z. Hardwaredriven crypto acceleration functions help reduce operations and maintenance costs.

AF_IUCV SOCK_SEQPACKET support: improves close collaboration between SUSE Linux Enterprise Server for System z and z/VM in the networking area. This provides better performance for intra machine / VM communication.

TTY terminal server over IUCV: provides central access to the Linux console for the different guests of a z/VM. Fullscreen applications like vi are usable on the console.

Enhanced HiperSocket support: Additional Layer 2 support for IPV4 and support for IPV6



SUSE® Linux Enterprise Server for System z 11 New Features in Service Pack 1 (c´d)

s390tools enhancements: package with a set of user space utilities. It is the essential tool chain for Linux on System z and contains everything from the boot loader to dumprelated tools for a system crash analysis

Large page support: enables better performance with large memory footprints like in Java or database workloads by exploiting new System z10 large memory pages (1MB)

Decimal Floating Point library support: libdfp including require glibc infrastructure for I/O.

Kernel vdso support: speed up gettimeofday, clock_getres and clock_gettime – more efficient time stamp generation.



SUSE® Linux Enterprise Server 11 Service Pack 1Scalability Today

• The only enterprise Linux operating system that helps customers

– Manage several workloads within one Linux instance in a lightweight manner by providing Kernel Resource Management with Control Groups

– Compute huge amounts of data in memory, e.g. in data warehouse and ERP systems, by supporting 16TiB RAM (and beyond) on certified hardware (System z limits apply)

– Improve efficiency by leveraging HW support for resource saving features due to the “tickles idle / timer patch” Kernel

– z10 scheduler optimizations and support for new floating point features improve performance and increase consolidation ratios

Novell Customer Center• Included at no cost with SUSE Linux Enterprise

Server and fully supportedBenefits

• Secure centralized deployment within the firewall• In cooperation with NCC, automatically assigns registration codes• Reduces bandwidth use • Accurately and automatically tracks entitlements• Uses your existing customer interface

Key Features• Staging of patches• Central deployment• Support of “sneakernet” configurations• Works with new integrated supportability infrastructure


Differentiators – Unique ToolsStarter System for System z

Historically, one of the biggest hurdles to implementing Linux on the mainframe has been gaining network access to the installation media from the mainframe (Installation routine cannot access builtin DVD reader, Firewall rule changes needed)

SUSE Linux Enterprise Server Starter System for System z is a prebuilt installation server — facilitates installation of SUSE Linux Enterprise Server for System z on a z/VM system

Eliminates the network access hurdle to try out Linux on the mainframe — gaining network access to the installation media from the mainframe

Allows customers with little or no Linux or z/VM experience to initiate evaluations of SUSE Linux Enterprise Server for System z
